Example of standalone Apache Qpid (amqp) Junit Test

Question

Does anyone have an example of using Apache Qpid within a standalone junit test.

Ideally I want to be able to create a queue on the fly which I can

Answer 1

Here is the setup method I use for QPID 0.30 (I use this in a Spock test but should be portable to Java of Junit with no problems). This supports SSL connection, the HTTP management, and uses only in-memory startup. Startup time is sub-second. Configuration for QPID is awkward compared to using ActiveMQ for the same purpose, but QPID is AMQP compliant and allows for a smooth, neutral testing for AMQP clients (obviously the use of exchanges can not mimic RabbitMQs implementation, but for basic purposes it is sufficient)

First I created a minimal test-config.json which I put in the resources folder:

{
  "name": "${broker.name}",
  "modelVersion": "2.0",
  "defaultVirtualHost" : "default",
  "authenticationproviders" : [ {
    "name" : "passwordFile",
    "type" : "PlainPasswordFile",
    "path" : "${qpid.home_dir}${file.separator}etc${file.separator}passwd",
    "preferencesproviders" : [{
        "name": "fileSystemPreferences",
        "type": "FileSystemPreferences",
        "path" : "${qpid.work_dir}${file.separator}user.preferences.json"
    }]
  } ],
  "ports" : [  {
    "name" : "AMQP",
    "port" : "${qpid.amqp_port}",
    "authenticationProvider" : "passwordFile",
    "keyStore" : "default",
    "protocols": ["AMQP_0_10", "AMQP_0_8", "AMQP_0_9", "AMQP_0_9_1" ],
    "transports" : [ "SSL" ]
  }, {
    "name" : "HTTP",
    "port" : "${qpid.http_port}",
    "authenticationProvider" : "passwordFile",
    "protocols" : [ "HTTP" ]
  }],
  "virtualhostnodes" : [ {
    "name" : "default",
    "type" : "JSON",
    "virtualHostInitialConfiguration" : "{ \"type\" : \"Memory\" }"
  } ],
  "plugins" : [ {
    "type" : "MANAGEMENT-HTTP",
    "name" : "httpManagement"
  }],
  "keystores" : [ {
     "name" : "default",
        "password" : "password",
      "path": "${qpid.home_dir}${file.separator}keystore.jks"

    }]
}

I I also needed to create a keystore.jks file for localhost because the QPID broker and the RabbitMQ client do not like to communicate over an unencrypted channel. I also added a file called "passwd" in "integTest/resources/etc" that has this content:

guest:password

Here is the code from the unit test setup:

class level variables:

def tmpFolder = Files.createTempDir()
Broker broker

def amqpPort = PortFinder.findFreePort()
def httpPort = PortFinder.findFreePort()

def qpidHomeDir = 'src/integTest/resources/'
def configFileName = "/test-config.json"

---

code for the setup() method:

   def setup() {

    broker = new Broker();
    def brokerOptions = new BrokerOptions()

    File file = new File(qpidHomeDir)
    String homePath = file.getAbsolutePath();
    log.info(' qpid home dir=' + homePath)
    log.info(' qpid work dir=' + tmpFolder.absolutePath)

    brokerOptions.setConfigProperty('qpid.work_dir', tmpFolder.absolutePath);

    brokerOptions.setConfigProperty('qpid.amqp_port',"${amqpPort}")
    brokerOptions.setConfigProperty('qpid.http_port', "${httpPort}")
    brokerOptions.setConfigProperty('qpid.home_dir', homePath);


    brokerOptions.setInitialConfigurationLocation(homePath + configFileName)
    broker.startup(brokerOptions)
    log.info('broker started')
}

---

code for cleanup()

broker.shutdown()

---

To make an AMQP connection from a Rabbit MQ client:

        ConnectionFactory factory = new ConnectionFactory();
        factory.setUri("amqp://guest:password@localhost:${amqpPort}");
        factory.useSslProtocol()

        log.info('about to make connection')


        def connection = factory.newConnection();
        //get a channel for sending the "kickoff" message
        def channel = connection.createChannel();
